    Study Notes

    Laws and Forces for New Drivers

    • Key forces for drivers include gravity, inertia, momentum, kinetic and potential energy, friction, and centrifugal/centripetal forces.

    Kinetic Energy

    • Energy an object develops while in motion; increasing speed significantly raises danger levels.
    • Doubling speed increases kinetic energy fourfold, resulting in quadrupled braking distances.

    Gravity

    • The Earth's attraction force affects vehicle handling, especially when downhill.
    • A vehicle's acceleration increases with gravity, potentially causing excessive speed.

    Managing Driving Downhill

    • Shift to a lower gear or gently apply brakes to maintain control and speed.

    Preventing Parked Cars from Rolling

    • Keep the car in low gear or 'Park' for automatics, apply the parking brake, and position front wheels to prevent rolling.
    • Turn wheels toward the curb when parked downhill, and away when uphill. Use a brick as extra safety on inclines.

    Newton's Law of Inertia

    • An object at rest will stay at rest, and an object in motion continues in motion unless acted on by an unbalanced force.

    Importance of Seat Belts

    • Seat belts prevent occupants from moving forward during sudden stops by providing necessary resistance.
    • Loose objects in the vehicle can become projectiles, causing injury during sudden stops — store them in the trunk.

    Potential Energy

    • The energy stored in an object due to its position or arrangement.

    Friction

    • Resistance that occurs between surfaces in contact, crucial for movement and control.
    • Essential for starting, stopping, and turning; proper lubrication is necessary to maintain effective friction in vehicle components.

    Traction

    • Factors affecting traction include stopping distance, centrifugal force, and hydroplaning; an increase in any can diminish traction and control over the vehicle.

    Centripetal Force

    • The force that changes the direction of a moving object along a curved path.

    Centrifugal Force

    • A pseudo force that appears to pull outward on a body in circular motion, increasing with acceleration; it's the reaction to centripetal force.

    Laws of Motion

    • For every action, there is an equal and opposite reaction, fundamental to understanding movement and collisions.

    Safe Cornering Guidelines

    • Decelerate before curves, brake gently while turning if necessary, and downshift in manual transmissions.

    Force of Impact

    • The impact force increases with speed; higher speeds result in greater collision impact and damage.

    Speed and Collision

    • Doubling a vehicle’s speed quadruples its force of impact in a collision.

    Impact in Vehicle Collisions

    • In collisions between vehicles at the same speed, the lighter vehicle experiences greater impact force relative to its mass.
